Hi to everyone. After an update I had no internet connection with the kernel 4.4.0-186 in my desk pc with an old 64 bit Pentium D. Usually I use a wireless N USB GNU/Linux adapter model TPE-150USBL by Thinkpenguin.com. I have removed the latest kernel and the desk pc now works very well with the kernel 4.4.0-185 and is perfectly updated. Is perhaps my wireless N USB adapter not suitable for that kernel? Thanks for the attention.

Hi again. I have noticed the same problem (no internet connection) with the kernel 4.4.0-186 even on an old 32 bit HP 510 notebook. On this notebook I usually use a wireless N USB adapter for GNU/Linux model TPE-N150USB by Thinkpenguin.com. Even in this case I have removed the latest kernel and the notebook now works very well with the kernel 4.4.0-185 and is perfectly updated. On an old 32 bit ASUS EeePC netbook the latest 32 bit kernel works well, no internet connection problem. It is strange.

I noticed this issue with my USB wifi on both my laptop and desktop. The laptop uses trisquel 8 and kernel 4.4.0-186-generic while the desktop uses Trisquel 9.0 and kernel Kernel 4.15.0-112-generic. I wonder if this has anything to do with this bug:

https://www.parabola.nu/news/ath9k-wifi-devices-may-not-work-with-linux-libre-576/

https://labs.parabola.nu/issues/2824

"if you have a USB wifi device which uses the ath9k or ath9k_htc kernel module, you should postpone upgrading to any of the 5.7.6 kernels; or the device may not work when you next reboot - PCI devices do not seem to be affected by this bug"

My PCI wifi works and my Manjaro desktop also doesn't work with a different USB wifi since upgrading to the kernel 5.7.9-1-MANJARO so it seems similar. My USB wifi does work with kernel 4.4.0-119-generic. I have just created an issue for this but wanted to share my findings here as well.

When I use ath9k-htc, I always need to first create a hotspot, then disable the hotspot and re-connect to WLAN. It's because that ath9k-htc firmware (albeit free/libre) doesn't work with MAC randomization. And this is why I always suggest that PCI/e-based ath5k/9k be used whenever possible (i.e. not restricted by firmware whitelist).

I have a single-antenna super low-end AR2427 from Asus eeePC, and it's still much better than AR9271.

Installing the linux-image-generic-hwe-8.0 package? See: https://trisquel.info/issues/27129

No, you do not. linux-modules-extra-4.15.0-112-generic, in dependence of linux-image-generic-hwe-8.0, is apparently the package providing the support: https://trisquel.info/forum/trisquel-software-update-broke-my-wifi-connection#comment-151114

Thank you, Magic Banana! My desk pc works well with the kernel 4.15.0-112. What can happen, if I decide to install the following suggested packages:
linux-headers-4.15.0-112-generic, linux-hwe-tools, fdutils ??
Another question: what is the package "thermald" and does "hwe" stand for hardware enablement?

Nothing but a small loss of disk space: if you do not know what an uninstalled package is for, then you usually have no use for it.

what is the package "thermald"

Its description says "Thermal monitoring and controlling daemon".

For details: https://01.org/linux-thermal-daemon/documentation/introduction-thermal-daemon

does "hwe" stand for hardware enablement?

It does.

Hello, Magic Banana. I have noticed the following situation:
If I uninstall the previous in use kernel 4.4.0-185, I get the usual annoyance by GRUB: " Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device ore file completions.
grub> _ "

If I reinstall the old kernel, the old laptop HP510 boots normally. Now 2 questions: What does it depend on? In these conditions is better having in use the old or the latest kernel?

As far as I know, GRUB boots by default the latest kernel, the one with the highest version. The GRUB_DEFAULT variable, in /etc/default/grub, can change that behavior: https://www.gnu.org/software/grub/manual/grub/html_node/Simple-configuration.html (if you modify that file, you then need to execute 'sudo update-grub' for the changes to be taken into consideration).

The other kernels can be booted from the "Advanced options for Trisquel GNU/Linux", in GRUB's menu.

Use a kernel that properly drives your hardware.

I.e. , in my case I have to maintain the old 4.4.0-185 and the latest 4.15.0-112 in my desk (and also in the notebook). Thank you for the attention, Magic Banana.
